Forgetomori has a nice photo gallery of giant earthworms. I'm not sure if they are real or not.
The worms in the images all look they are up to a meter in length, compatible with the recorded dimensions for the many species of the families we discussed. They are probably real, though exactly from where and what species my ordinary investigation didn't come up with. Specialists, do enlighten us with further confirmation and identification! The first image of a girl holding up one, for instance, may not be of an earthworm but of a caecilian.
